RHS Chelsea Flower Show

Over the 11 acres of grounds at the Royal Hospital, visitors can see a wide range of spectacular show gardens and floral exhibits at this annual horticultural show. It's strictly advance-booking only, with no admission on the gate. The first two days are reserved for RHS members and it's probably worth joining just to see everything at its freshest. The booking slots are 8am-8pm, 3.30pm-8pm, 5.30pm-8pm. On the final day the show closes at 5.30pm and from 4pm there are great bargains to be had when exhibitors start to sell off their plants.
